Restructuring project folder
The project folder got restructured for better overview over the project and to be able
to better tell the different components apart.
- YARD documentation removed from root of the project, YARD will only be used for the backend documentation
- The backend got moved into backend/src and backend/tests to get all files of the backend together in one place.
- mysql got renamed to database for possible future changes to the database
Automation paths updated
The path in the automation scripts were changed to reflect changes to the project structure
